Ut High Capacity Double Roller Crusher for Coal Limestone Primary Crushing

The Double Toothed Roller Crusher is designed for primary and secondary crushing. The teeth can bite into larger materials and use shearing and stretching forces, making it far more effective for Coarse Crushing of materials like Coal and Soft Rock compared to smooth rollers.

No. One of the greatest features of the Double Toothed Roller Crusher is its self-cleaning ability. The relative movement of the teeth ensures that sticky or wet materials are forced through without building up on the roller surface, preventing clogging.

Yes. We offer Replaceable Tooth Plates or Individual Tooth Sleeves. You don't need to replace the entire roller; you only need to swap the worn parts, which significantly reduces maintenance costs and downtime for your Mining Operation.

Our Double Roll Crusher is equipped with a Safety Spring or Hydraulic Protection System. If an unbreakable object (like a piece of iron) enters, the rollers will automatically retract to let it pass and then return to their original position to continue crushing.

This machine is famous for its Low Over-crushing Rate. Because it uses shearing force rather than pure compression, it produces very little fine powder (dust), ensuring a high yield of the required grain size for Coal and Coke.
